Default PYPES users reviews?

I am ready to pull the trigger on a dual exhaust Pypes, 409 SS with a pair of Hi Flow Metal Substrate Cats... CVM11K and SCC40R

Do they come as good fit out of the box and,,, I have the Magnaflow SS exhaust now, should I keep the Pypes muffler or cut them off and put the Magnaflows on or use the Pypes muffler, the Pypes is a Single tube exhaust and the Magnaflow is a dual

Mine is a true dual . Clamps loosen up a couple times . In a as delivered length they stuck out damn near 4 inches , not my preferance . I cut them down .
No drone no cats , love the sound .

Pypes will certainly have more flow than my Y-pipe!

I'll post pics and sell my cat back / SS Magnaflows in a few days.

I bought their kit for the wifes 05 Mustang. Had an X pipe and all stainless. It fit nice and the workmanship was very good.

Like Ron said, lots of good reviews on A body cars. Those guys love PYPES.

I installed a Pypes system on my 1985 Monte Carls SS about a year and a half ago. The fit and quality was great!

I have a set w/X-pipe on my '90. Great fit, great sound. The flange pulling the downpipe into the stock manifolds were drilled incorrectly, too narrow, and Pypes would not make that right. We just had the holes elongated but it would have been nice to skip that expense in the first place.... Hope this helps

My Spiral Metal Cats arrived today,,

It would be awesome if the cats go onto the Pypes and headers and align well so I cna just use band clamps.

Thanks Larry! And you were running a single before? Should be a nice improvement on two counts, looking forward to seeing the whole system.

I'm connecting to headers so this is not an issue for me.
